Hello
I am working on a project of a 100 watts pure sine wave inverter, using DC to DC converter (push-Pull topology) as a supply for the H bridge (from 24 to 80 V ), the H bridge is controlled using mbed microcontroller. everything works fine till I connect the LC filter it draws large amount current without any load.
switching frequency=16KHz
Can anyone help me please.
